Abstract :
The cardiovasculogram (CVG) is the graphical depiction of the electronic signals generated by the technique of impedance cardiography (ICG) by measurement of the mechanical function of the cardiac cycle. Previous studies have suggested that the presence of a prominent ldquoOrdquo wave in the CVG may be a sensitive indicator of fluid volume overload during episodes of decompensated heart failure. In this study, a computer model of a circulatory system interfaced with a simulated bioimpedance technology is used to determine which physiologic elements may be associated with the typical changes seen in the CVG during acute heart failure.
